I bought an Y580 Laptop last year. After approx. 6 months of usage, i have the following problem, my Video Card Nvidia GeForce 660M GTX disappears after a few minutes/hours. Sometimes after an hour, sometimes much earlier. The video card is everytime in idle mode when this happened and not in use. It disappears from the device manager in Windows 7 too. Only a reboot brings it back. A reinstall of the video card drivers didn't solve the problem.

Are you sure? No any gpu monitoring/ temp apps? then try isolating the problem, by booting it in safe mode, then go idle.. then observe.
That was my problem before, gtx 600m disappears within device manager, the cause was gpu temp monitoring app when in idle mode.
